Mean Well PSC-35 35 W security power supply

The Mean Well 35 W PSC-35 series security power supply features the primary output as well as an additional charger output with a relatively small current, which can be used for DC UPS applications with a back-up battery. The range is suitable for low-power security applications; small-scale battery back-up projects; emergency lighting systems; alarm systems; DC UPS systems; central monitoring systems; and access systems.

The product is available in either the PCB type or the enclosed type (with L-bracket and cover) form factors, giving greater flexibility when it comes to security system designs. It has an input range from 90 through 264 VAC and there are two output options: 13.8 VDC (adjustable range 12-15 VDC) and 27.6 VDC (adjustable range 24-29 VDC). These cover the most frequently used voltages seen in security applications.

The series has an efficiency rating of up to 86% and can operate between -30 and +70°C under free air convection. It has been designed complete with short-circuit, overload, overvoltage and battery-low protection. A fuse protects against battery reverse polarity.
